Let's draw a diagram of this room so it's easier to solve. (see the image I've included)
The perimeter is the length of all of the sides of the rectangle, so
8 + 8 + x + x = 40
Simplify
16 + 2x = 40
Subtract 16 from both sides
2x = 24
Divide by 2 on both sides
x = 12
The length of the rectangle is
12.
Hopefully this helps! If you don't understand or have more questions, feel free to DM me!! :)
Answer: -3/2
Step-by-step explanation: the slope is calculated by the formula:
(y2 - y1)/(x2-x1)
So, (-1-8)/(-3-(-9)) = -9/6 = -3/2
Answer:
c
Step-by-step explanation:
i just looked up the question
21.5 inches long
12*3/8=4.5
26-4.5=
